Be it known that I, A ERT R'. Granier- MAN, a citizen of the United States, residing 'in Philadelphia, Pennsylvania, have invented certain-Improvements 1n Brick-Cleaning Machines, of which the following -is a speci- My invention consists of certain improve'- f'or Eette'rs" Patent filed ,September Serial No; 721,176,.the objects of ct the operation of -the inachine and'to render such operation'p-erfectly safe.

:These objects I attain in the manner here- `ina'fter set; forth, referencev being had to' the i trating in r different relations :to one a certain cam-and a lever for moving one of.

ac ompanyingdrawings, in which-d Figurel is a. plan or top view ,of themachine; Fig. 2 is-a side elevation of the same looking in the direction of the arrow w, Fig. 1; Figs; 3 and 4 are. side elevations, on a larger-scale, illustrati-ng the operation of a certain die and ram whereby the preliminarycleaning of a-portion. of the brick is ef'- fected; Fig. 5 isa top-view of said' preliminary cleaning'die and ram 5' FigA .6 is a perspective view of the brick after. lthe prelimi nary. cleaning of the samehas been effected; Fig. 7 is a longitudinal section of the main cleaning die illustrating alsothe--manner of applying the partially cleaned brick thereL to; Figs. 8, 9, 10 and 11 are diagrams illus another the sides of the final cleaning die,- and Fig. 12 is a perspective view on a larger` scale of said lever.

In Figs. 1 and 2 of the drawings, 1 rep` resents .the main frame, 2 a sliding plunger with a projecting ram 3, 4 a crank' shaft,and 5 a connecting rod whereby the reciprocation of such plungerby means of said crank shaftfis effected, all of these parts 'being common andv therefore requiring no tur-- ther or more detailed description.

-Mounted upon the main frame, atwone side of the machine, 'are/three. die plates .6,

"'-ner edges ad:

7 and 8, the'die plate 8 being vertical and the die. plates 6 and 7 .horizontal and disposed 'one above another and with their in {acent to the face of the die plate S. The actingv'faces of all of the plates.6,-.7' vand, 8 are toothed, as shownin Figs, 1' and, 5,-,and the upper horizontal Speccaticn of 'Letters Patent.

Projecting' Vfrom-one side of the plunger .through a suitablev spending sideof th arm 10 which carries a ram 11, the latter,

on `the back strokeof the plunger, being adapted Ito pass between the die plates 6 and 7 andl in frontof the die plate 8 at the side ofthe machine. The die plates 6 and 7 are relatively shallow butI can receive between them a few inches of ,one end" of the brick tov .be cleaned,- zin'd.l the acting faces of'sad vplates are tapered so as'to be fhrther sepa. 4rated from oneanother at one end than at'r the other, as shown lin Fig'. Anattend- 'ant grasping an uncleanedibrick at one end can, there-fore, without anyf risk of injury, place itsopp'osite end between the die` plates Gand 7 and in front of the ram 11, as shown' 'in Fig. 3, .thefront end of the brick bearing such relation totheface of the die plate 8 that, when' thel brick is .thrust bythe advancin'g ram 1]. betweenthe plates Gand" 7 and acrossthe face of the plate-8,the adhering mortar will be cleaned from r'the front end of,'t,he .brick-.and also from the top .and -bottom faces of theI brick for a distancey of .an inch'or more backfrom the front end',I as shown in -Figs. 5 and 6.

The finishing .die `1 2 is carriedby a slide i 13 .w'4hich is suitably guided on a transverse structure 14 at oneendof the frame, recip'- rocating movement being imparted. to this 'slide ---at intervals .by any suitable mecha'- nism operatingin conjunction with the p lun? gerQ, for instance, by the mechanism shown and described in my application before freferredv to, this movement being such that at one. of its terminations the die 12 will bein line with the ram 3 of the plunger and at .the other of its terminations said die will be'at one side of the machine and yout of the path of theplunger, as shown in li`ig.'1.

. 'The finishing die is composed of opposite side plates 15, abottom plate 16 and atop platel, the bottom plate 16 being 'rigid but` the ,top plate 17 lbeing pivoted at the-rear end and 'normally depressed bythe action '-'Ihe top plate'l' can, however, be raised,

"when desired, lagainst .the 'pressur f 'the spring ,l8, the means employed in t e pies' ent instance for this purpose being a rod 19 per end to the forward arm of a lever 20 which is pivotally mounted upon a 'standard -21 projecting upwardly from the slidell, 'as shfown in Fig. 7. i

'a-carn bar 22 xedly mounted upon the top 15 ofthecrossiframe 14. Therear arm of the lever has .a'hinged section23 (Fig. ll12) normally kept -in lilne with the rest of the arm by a 'spring 21 but capable of yielding upwardly when subjected to pressure' from zobelow. n IThe actionof the cam bar upon the lever '20 is as foll'ows, reference being had to Figs'.

\ 89, 1O and 11:.Yi7hen the sidel is at that llimit of its movement wher .line with't-he ram 3 the lever 2O occupies the relation to thecam bar 22 shownv in Figj'S, t-hat is 4to say, it is 'b'eyond the end of the cam bar vand its rear arm -is below the under surface of the elevated end of said cam bar.

'30 Asjthe die carrying slide 13 moves to the left, the le 'fer 20 -is ,carried 4beneath the cam' bar 22, as s iown in Fig. .9, and is acted upon thereby s'oas to depress the rear' arm of the lever andraise'the forward arm ofthesame,

l thereby lifting t-he upper die plate -17 Saidupper die plate vis retained in the elevated po'- sition until the slide 13 has almost reached i the limit of its movement to the left, whereupon the rear arm of the lever 20 passes 40 from under the cam bar 22, `as 'shown in Fig. 10, and', being free to rise, permits the upperdie plate17 to 'be depressed by the spring 18. On the movement of the slide- 13 to the right the rear arm of the llever 20 passes over .the top of,the cam bar'22 yand its piv-4 ot'ed 1nember1-23- is raised by Contact with lthe eleratediendwf said. cam bar, as shown in Fig'll, but when thelever passesbeyond `the cam bar, said"pivoted'n.ernber snaps back to its normal position so as to pass belneath the cam bar on the next movementof` the slide 13 to the left. v

Inm'iediatelyl in front of the die 12, when the latter is inthe position-shown in Fig.' 1, is a rail lor bar 2G which is flush with or slightlyaborethe bottom plate 16 of the die. cleaned brick, such as shown in Fig. 6. may,

' therefore, rest the cleaned end of said'brick on said bar so that saidv cleaned 'end willl project beyond -the bar and toward the die 12, this cleanect,`fprojecting portion of the brick, when the die 12 reaches the position shown in Fig.-1-., being between the forward ends `upon the top 0.

An attendant holding '-a partially" ofthe lower and upyier plates' and 176i 65 i -the die, as` shown in. 1.37. j

vAs the, die' onf-its moygementgto the left approachesthe brick the upper die plate v17 is raised so 'hs to be free froincontact with the upper face of' the brick, but, 'just as the. die.4 7 0. .i

'reaches thelimit of. its movement, the 'le'ver 20"-1l passes'frorn lander the iniuence of the cam bar 22 andthe u yper die plate 17 snapsdownfp the brick and'securely con-.

'75 plates of the die, whereby, as the 'die moves fronrr they side of the machine- .to'ward the.'

center'of the same, it .will-'carry the partially cleaned brick 'with it, and will stop` with the brick' inline with lthe ram 53. When 'the ram i 80 advances, therefore,it will strike the rear end of the brick andiwill force the same through the die so as tofremove the m'ortarfrom the right and 4left hand sideslof the brick and complete the re oval of the mortar from the top and botto-msides of the same.

It will be' noted on reference to Fig.- 7

.-thatthe top and \bo tt0m plates bf thedie' 12 project beyond the sideplates 15, consequently the presenfc'e of mortar up to the end -90 of'the brick on those sides which correspond with the side plates 15 of the die will not interfere with the proper placing ofthe par-4 tially cleaned-end cfthe brick between the Vupper and lower pilates of the die. jv .'If desired, a bari or rail 2 7 may be dis-` posed above .the rai 26 for' contact with the cleaned top face If'the brick when the a cleaned lower face ef' the same rests on said rail '26, thus serving to support the partially cleaned, brick in position to be engaged by -the top and -bottoinf plates of the die 12,' 'even should the attendant let-` go of the brick bcfore the die reachesthe proper positionto engage the same. The-rails 26 and 27 may" A105 be mounted upon the main' ,frame 1 ofthel nachine in 'any manner 4which, will Apermit the-lateral movement of the brick from be-v tween the same. j "V The machine Ais intended to be epe'rated by two attendants o ne of whom, located 'at`one side of the machine, .presents the bricks to the preliminary cleaning'die and, after the partial cleaning of the brick, -placs it in'. position to be handled by the other attendant, located at the opposite side'of the m'a-V chine, the latter 'attendant presenting the partially cleaned brick in position-,to be. clamped between the plates 1G and'17 of the finishing die 12. In neither case, however, are the hands ofthe attendants brought into position to be s'truck 'by a moving part'of the machine, or caught betweenaxed and. a moving part ofv the same,l 'and all risk of injury to either attendant' is thereforel crei-,l 125 cleaning bricks, of means for 4cleaning l,the mortar 'from opposite sides of ,thev brick at and nea-rene end ofthe same, a die adapted to engage I said cleaned surfaces. ofthe brick,y and means for forcing the brick through said 'die sofas to'comp'lete vthe cleansof themortar from said partially cleaned sides thereof. j The combination, in ,apparatus for cleaning 'loricks,- ofl mea-ns for cleaning the .mortar from `opposite sides.` of I thel fbi-ick atand near one end of the same,
